2 Robustness and reliability Are you looking for the most robust, maintenance-free and cost-effective encoder? Then the 800 series is for you it s the first choice of most engineers! The product series has a long history of successful operation in applications within heavy industries, such as the steel, paper and wind power industries. These applications place stringent demands on robustness and reliability, and the encoder is designed thereafter. Mechanically it features a dual set of heavy duty bearings and a well-encapsulated enclosure. The electronics are designed to withstand an environment where it is exposed to powerful vibrations, electronic disturbances, etcetera. The 800 series can also be equipped with Leine & Linde s advanced diagnostics system, ADS, for condition-based maintenance. The ADS system constantly monitors the encoder s key functions and is fully integrated into each encoder. In case an impending fault is detected a warning signal is immediately generated. This enables service that is only performed as necessary and that can be planned in ample time to avoid unforeseen breakdowns. 3

This solution provides added safety in the form of redundancy, the outputs are based on two separate scanning LED:s and electronic circuits. The outputs are galvanically insulated from each other and may be connected to two separate systems for different function or for redundancy. Available in model 855 and

6 Sine wave signals Sine waves are an alternative form of output signal. The analogue signal produces a unique amplitude for each position on the wave, allowing interpolation and very high resolutions. The interface 1 Vpp is often used in safety-critical applications where detection is required of extremely small movements. Code keys Available in model 850, 861 and 862 ADS Classic ADS is an Advanced Diagnostic System that continuously monitors the encoder function. If the encoder is nearing the end of its life, a warning is transmitted, enabling action to be taken in good time before problems arise. This system is integrated into the encoder and is used in applications with high demands for reliability, for example, in motors for continuous operation at a paper mill. Available in model 841, 850, 861 and 862 Digital speed over PROFIBUS With this option the encoder has two different connections, one with a standard incremental output and another for communication over PROFIBUS. The standard incremental pulse output is used for connection to the inverter for direct speed control, while the additional PROFIBUS output can be connected to another system where a reference value of the speed is required. The speed is calculated internally in the encoder and is sent over the fieldbus.
